Fix sleep issue

Look for S3 sleep fix here: https://wiki.archlinux.org/index.php/Lenovo_IdeaPad_5_14are05#Suspend_issues_(S3_sleep_fix)

Setup performance mode and battery toggles

1. install acpi_call (or acpi_call-lts for LTS kernel, acpi_call-dkms for other kernels)
2. copy ideapad5_trick.sh to your home dir
3. run chmod +x ideapad5_trick.sh to make it executable
4. run ./ideapad5_trick.sh
